TENOVA. innovative solutions for metals and mining
Optimal Solutions for Mining, Material Handling and Processing
TAKRAF is a key supplier of equipment and systems for open pit mining and bulk handling, having provided hundreds of complete systems, as well as individual machines, to clients all over the world. Based upon more than a century of experience and know-how, the product range stretches from overburden removal, raw material extraction, conveying, processing, comminution, homogenizing, blending and storage to onward transport or shipment.
TAKRAF provides the full range of services, from project studies, planning, engineering and design to fabrication, supply, erection and commissioning, technical assistance, service and after-sales service for plants, systems and equipment. Its equipment has proved robust and reliable in adverse geological conditions, in extreme climates with temperatures down to minus 45°C, in dust, wind or extreme humidity, as well as in seismic zones and altitudes of up to 5,000 m above sea level or in underground applications.
TAKRAF has committed to both environmental and social sustainability in their business interactions and has adopted a Zero harm approach to safety under the SAFETY FIRST promise of Tenova.
TAKRAF, a Tenova company, is an integrated solutions provider to the global mining, bulk material handling, minerals processing and beneficiation industries, offering innovative technological solutions as well as process and commodity knowledge along the industry value chains. With the integration of the well-known DELKOR and Tenova Advanced Technologies (formerly Bateman Advanced Technologies) brand of products into TAKRAF as specialized product lines, our portfolio for the minerals processing and beneficiation sectors has been considerably enhanced.

The apron feeders are available with frequency controlled electro mechanical drive or hydraulic direct drive.
n Robust construction using high strength materialsn Standard bearings and plummer blocks on head and tail shaftsn Standard crawler under-carriage partsn Lifetime lubrication on rollersn Range of standard widths available in different lengths, as required n Flight overlap minimizes spillagen Sprocket segments interchangeable and easily replaceablen Easy chain tensioning at tail shaftn Compact hydraulic or electromechanical drivesn Drives can be fixed or variable speed; single or twin drivesn Heavy duty ribbed pans are standard
n Can be transported and installed as fully assembled and tested unitn Moving parts available worldwide, off the shelfn Variable speed drives and short chain pitch provide accurate and infinitely variable feed ratesn High impact carrying capability due to closely spaced rollers and impact railn Manual or electronic control – locally or remote – ensuring flexibilityn Height saving benefits due to feeder inclinen Minimal scheduled maintenance requirementsn Discharge also of ‘sticky’ materials through appli- cation of bulk solids flow designn Long service life
Besides the standardized apron feeders TAKRAF supplies heavy duty apron feeders designed to meet special re-quirements resulting from conditions given by material, capacity and geometry. For capacities requiring chains above D11, please contact TAKRAF GmbH.

The apron feeders are available in outboard design with the chains outside the area in between the skirt boards preventing chains and rollers from falling spillage material and inboard design providing shorter and lighter pans. For outboard designs, return rollers are mounted at the pans or mounted underneath the pans as for inboard chains. If mounted at the pans, the rollers move on a rail. Pans are heavily reinforced. As appropriate, greased slide rails are mounted in full length.Drive shafts are in one piece design. For large bearings, heavy plummer blocks are fabricated by TAKRAF in its own workshop.Chain tension is applied by screw type tensioning or with a tension frame (idler wheels mounted in it), hydraulically supported, mechanically secured. Chain force monitoring is available.
